Israel Regardie (1907-1985) was an Adept of the Golden Dawn and he was one of the greatest exponents of the Western Esoteric Tradition of the 20th century. He was also an initiate of Aleister Crowley's Order of the A.·. A.·., and he was a IXth degree initiate of Crowley's O.T.O. It was his aim to preserve the teachings and work of the Golden Dawn and Aleister Crowley. His success in this task has profoundly influenced occult thought. From the age of 21, Regardie worked as Crowley's personal secretary. During this period, until their bitter parting, Regardie was one of the few who knew Crowley well. He was one of the few who were qualified to provide first-hand, personal insight into the character and personality of one of the major figures in Western Magick. In addition to his extensive writings, Regardie practiced as a chiropractor and as a neo-Reichian therapist. He taught Psychiatry at the Los Angeles College of Chiropractic and contributed articles to many Psychology magazines. Regardie's most profound work, The Complete Golden Dawn System of Magic, is a 1200 page book published by New Falcon Publications; a company he founded with his student Dr. Christopher Hyatt. The book is currently available in three different editions: a) 1200 page hard bound with index; b) eBook with the same material; and c) a new portable edition as a soft cover. Today Regardie's work is being preserved and perpetuated by New Falcon Publications and the Israel Regardie Foundation. Lon Milo DuQuette lives in Costa Mesa, California.
